SAFETY LAMP-BURNER.

S ecfcatien of Letters Patent.

Patented Mar. 2er, 1914.

Application led December 27', 1912. Serial No. 738.862.

I'e it known that I, Ciinis'iori-inu l. J. Ti'i'riioxo. a citizen of theUnited States, residing at Sun Antonio, in the county of Bexar and Stateof Texas, have invented new and useful iiiipi'ovenients in SafetyLamp-Burners, of which the following is a specification. i

This invention relates to lamp burners, the object in view being topi'ovide a safety lamp burner embodying, in connection with the usualelements, a self-balancing flame extinguishing cone, which, when thelamp is orerturiied or subjected to an unusual agitation or shaking,tumbles over the wick and serves to instantly extinguish the flame,thereby preventing serious accident.

lilith the above and other objects in view, the invention consists inthe construction, combination and arrangement of parts, as will behereinafter more fully described, illustrated in the accompanyingdrawings, and pointed out in the claim hereunto ap pended.

In the drawings: Figure l is a diainetrical section through a lampburner, showing the present invention applied thereto. Fig. 2 is asimilar view taken at right angles to Fig. l. Fig. 3 is a detailperspective view of the extinguishing cap. Fig. 4 is a detail sideelevation, showing the openings which re ceive the balancing' feet ofthe cap. Fig'. 5 is a sectional view similar to F ig. l, showing amodified arrangement of the extinguishing cap. Fig. 6 is a detailperspective view of the extinguishing cap under the arrangement shown inFig. 5. Fig. 7 is a detail per spective view of the cap support.

rlhe main body of the burner l is of the usual form or construction,being provided with the chimney supporting flange 2, the perforatedfloor 3. and the wick tube 4t, in which the wick of the lamp is mountedand adapted to be slid up and down.

5 represents the usual cone provided with the flame orifice 6.

In carrying out the present invention, the body of the lamp is providedat diametrically opposite points with rectangular openings 7. the samebeing adapted to receive the oppositely projecting feet 8 oftheextinguishing cap, illustrated in detail in Fig. 3.

rl`he flame extinguishing cap comprises a dome-shaped body 9 having acentral flame orifice lO which is n'iaterially larger than thecorresponding orifice G in the cone 5, so as not to interfere in any Naywith the flame, when such extinguishing cono is in its normal position.

rl`he extinguishing cap is arranged within and under the cone 5, and isof such size that it may readily tip over to one side or the other. Thebalancing feet 8 are suiciently wide and fiat to rest in the bottoms ofthe rectangular openings 7, as shown in Fig. d, so that theextinguishing cap will remain in a central position until the lamp isagitated or shaken. whereupon the cap 9, by reason of its high center ofgravity. will tip over to one side or the other, thereby causing thedome-shaped body to snuff out the flame before an accident occurs.

Another form of the device. embodying thc same principle. is illustratedin Figs. 5, 6 and 7, in which ll designates a support for theextinguishing cap, the same being in the form of a rectangular sleeveadapted to fit over and be frictionally retained on the up per end ofthe wick tube fl. This support is provided with the oppositely andoutwardly extending horizontally flat balancing feet l2, whichcorrespond with the feet 8 shown in Fig. 3, being for the same purpose.The cap shown in F 6 is provided with rectangular openings 13corresponding with the openings 7 in Fig. 4, the openings 13 beingdesigned to receive the balancing feet 19.

By reference to Fig. 5, it will be seen that the outwardly extendingbalancing feet l2 pass through the openings in the extinguishing cap,and render the action of the tilting extinguishing cap exactly the sameas that described in connection with Figs. l to fr, inclusive.

l/Vhat is claimed is:

In combination, a base plate. a wick tube projecting above said baseplate, a substan tially dome-shaped hood fixed upon said base plate andsurrounding said wick tube, said hood being formed at diametricallyopposite sides with rectangular openings, a dome-shaped extinguisher.oppositely arranged lugs formed upon the extinguisher and arranged toseat upon the edges of said opening, said opening being relatively Intestimony whereof I @Prix my signature largerthan the thickness of saidlugs, and in presence of two Witnesses.

right angular feet formed on said lugs, said extinguisher being spacedconeentrieally CHRISTOPHER B' J' WITMOND .5 from said hood, said feetarranged to fricfitnessesz tionally engage the body of said hood at op-T. H. BRowNE, posite points. J. W. ETHERIDGE.
